Replacing Older Bosch Tankless with The Bosch Therm 830ES

The Bosch Therm 830ES Non-Condensing tankless water heater is a top performance, gas tankless water heater from Bosch. This 175,000 BTU heater is designed for residential applications and can deliver hot water up to 140 degrees F with a 8.3 GPM flow rate at a 35 degree rise.  Not approved for space heating applications.
This Energy Star approved tankless water heater can produce enough hot water for 2 major applications in most homes.

The Bosch Therm 830ES heater features an electronic ignition system and can vent through either 3 inch or 4 inch diameter stainless steel vent pipe either through the side wall or up through the roof. A stainless steel concentric side-wall venting option (ESHCK-Full-Kit) is also available.

The Bosch 830ES heater comes with built-in Freeze Protection but it does not come with the 3/4" PRV and the External Water Filter.  The freeze prevention kit is designed to provide protection for the water heater down to approximately 5°F for short term conditions only. It will not protect the appliance in areas where the temperature is routinely expected to be below freezing.  The freeze prevention kit will not protect plumbing outside the appliance from freezing.

The Bosch Therm 830ES is a wholesale model heater and sold to licensed plumbers and contractors.  The new Bosch Therm 830ES is a close replacement for older models such as the Bosch 250SX/250SXO, 635ES/635ESO and the 2400E.  Please be aware the 830ES is 7" taller, 2.375" wider and 2.75" deeper than the previous models. The Bosch 830ES is a direct replacement for the Bosch 2400ES.  For outdoor installations the Bosch 830ES would require the BTOK Outdoor Kit.

The Bosch Therm 830ES comes with a limited 15 year warranty on the heat exchanger and 5 years on all other parts.  Service and labor costs are not covered.
